Detailed Embodiments

[0022] The present invention will be described in detail below in conjunction with the embodiments shown in the drawings. However, this embodiment does not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on this embodiment is included in the protection scope of the present invention.

[0023] Reference Figures 1 to 3 As shown, the automatic winding and collecting mechanism 100 for flexible substrate tape loading provided by the present invention is used to assist in the winding and collecting of the tape, and can be specifically applied to the process of collecting COF tape using a reel. The automatic winding and collecting mechanism 100 for flexible substrate tape loading includes a first guide wheel 1 and a second guide wheel 2 arranged adjacent to the first guide wheel 1 in the radial direction. A channel 101 for the tape to pass through is formed between the first guide wheel 1 and the second guide wheel 2.

[0024] The first guide wheel 1 and the second guide wheel 2, the first guide wheel 1 and / or the second guide wheel 2 are axially movably arranged so that the position of the tape passing between the first guide wheel 1 and the second guide wheel 2 can be adjusted. Among them, the axis lines of the first guide wheel 1 and the second guide wheel 2 are parallel to each other. The aforementioned "radial direction" refers to the direction in which the first guide wheel 1 and the second guide wheel 2 are perpendicular to the axis line.

[0025] In this embodiment, the first guide wheel 1 includes a first sub-wheel 11 and a second sub-wheel 12 that are relatively independently arranged along the axial direction. The second sub-wheel 12 can move axially towards or away from the first sub-wheel 11; the second guide wheel 2 includes a third sub-wheel 21 and a fourth sub-wheel 22 that are arranged opposite to each other along the axial direction. The third sub-wheel 21 cooperates with the first sub-wheel 11, and the fourth sub-wheel 22 cooperates with the second sub-wheel 12. Obviously, the aforementioned "axial direction" refers to the extending direction of the axis lines of the first guide wheel 1 and the second guide wheel 2.

[0026] The second sub-wheel 12 is formed with an adjusting plate 121 on the side of the channel 101 away from the first sub-wheel 11, and the fourth sub-wheel 22 is formed with a groove 221 that cooperates with the adjusting plate 121. On the side of the second sub-wheel 12 facing the first sub-wheel 11, a first cam 122 is further formed, and on the side of the fourth sub-wheel 22 facing the third sub-wheel 21, a second cam 222 is formed. At least part of the channel 101 is located between the first cam 122 and the second cam 222. That is to say, the first cam 122 and / or the second cam 222 can support the established tape passing through the channel 101. In particular, the fourth sub-wheel 22 can also be axially movably arranged, and the second sub-wheel 12 can drive the fourth sub-wheel 22 to move together when moving axially. A coordination groove 211 that cooperates with the first sub-wheel 11 is formed on the outer periphery of the third sub-wheel 21, which can better maintain the relative position relationship between the first guide wheel 1 and the second guide wheel 2.

[0027] The automatic winding and collecting mechanism 100 for flexible substrate tape loading further includes a first mounting component 3 for mounting the first guide wheel 1, a second mounting component 4 for mounting the second guide wheel 2, and a substrate 5.

[0028] The first mounting assembly 3 includes a first mounting arm 31, a slider 32, a first rotating shaft 33 and a second rotating shaft 34. The slider 32 can move axially towards or away from the first mounting arm 31. The first rotating shaft 33 mounts the first sub-wheel 11 on the first mounting arm 31, and the second rotating shaft 34 mounts the second sub-wheel 12 on the slider 32. The first rotating shaft 33 and the second rotating shaft 34 are coaxially arranged. The first mounting assembly 3 further includes an adjusting knob 35 and a guide rod 36. The adjusting knob 35 is used to adjust the axial distance between the slider 32 and the first mounting arm 31. The guide rod 36 connects the slider 32 and the first mounting arm 31 and extends axially. Exemplarily, the adjusting knob 35 is set as a bolt, and the bolt axially penetrates the slider 32 and is connected to the first mounting arm 31. The guide rod 36 is provided in two and is respectively located on both sides of the adjusting knob 35.

[0029] One end of the first mounting arm 31 protrudes towards the substrate 5 to form a fixing seat 311. The fixing seat 311 is fixed to one side of the substrate 5 by fixing screws 312, and at least two fixing screws 312 are provided. The first rotating shaft 33 is arranged at the other end of the first mounting arm 31 far from the fixing seat 311.

[0030] The second mounting assembly 4 includes a second mounting arm 41 and a rotating shaft 42. The second mounting arm 41 has a first end 411 rotatably connected to the substrate 5 or the first mounting arm 31, and a second end 412 for mounting the rotating shaft 42. The third sub-wheel 21 and the fourth sub-wheel 22 are both mounted on the rotating shaft 42. In this embodiment, a connecting seat 313 is further provided at one end of the first mounting arm 31 close to the fixing seat 311. The second mounting arm 41 is rotatably mounted on the connecting seat 313 of the first mounting arm 31. That is to say, the second end 412 of the second mounting arm 41 rotates around the first end 411, so that the second guide wheel 2 moves towards the first guide wheel 1 and forms a channel 101 for a given strip to pass through with the first guide wheel 1. Here, the second mounting arm 41 is directly mounted on the first mounting arm 31, and the second mounting assembly 4 can be integrally mounted to the substrate 5 with the first mounting assembly 3 at one time, which is convenient for disassembly, installation and maintenance, and can also better avoid assembly errors.

[0031] The automatic material collecting mechanism 100 for feeding a flexible substrate tape further includes an elastic member 6. The elastic member 6 is connected between the first mounting assembly 3 and the second mounting assembly 4 and is used to drive the second guide wheel 2 to approach and press against the first guide wheel 1. Specifically, the first mounting arm 31 further forms a first connecting portion 314, and the second mounting arm 41 further forms a second connecting portion 413. The elastic member 6 can be set as a tension spring, and the two ends of the tension spring are respectively connected to the first connecting portion 314 and the second connecting portion 413.

[0032] To better avoid the abnormal winding of the tape around the second guide wheel 2 after passing through the channel 101, the automatic material collecting mechanism 100 for feeding a flexible substrate tape further includes a stop bar 7 mounted on the second mounting arm 41. Of course, according to the transmission path of the tape, the mounting position of the stop bar 7 can be reasonably adjusted.

[0033] The invention also provides a production device, including a cabinet 201, a reel (not shown) for collecting the tape, and the automatic material collecting mechanism 100 for feeding a flexible substrate tape as described above and provided at the incoming material end of the reel. It should be noted that Figure 4 only a partial structure of the cooperation and installation of the cabinet 201 and the automatic material collecting mechanism 100 for feeding a flexible substrate tape is shown; the aforementioned reel is usually arranged above the automatic material collecting mechanism 100 for feeding a flexible substrate tape.

[0034] The production device further includes a detection device arranged in the cabinet 201. The detection device includes a tension detection component 202 arranged beside the automatic material collecting mechanism 100 for feeding a flexible substrate tape and a position detection component (not shown) arranged at the bottom of the cabinet 201. The tension detection component 202 is specifically arranged near the tape transmission path and can detect the abnormal tension of the tape in real time; the position detection component can be selectively installed at the position where the tape naturally hangs down. When the tape cannot be normally collected but the incoming material end continues to feed the material, the position detection component can timely judge such abnormal situations. In short, the detection device can better avoid the abnormal transmission of the tape and reduce the on-site material loss.

[0035] In summary, the automatic material collecting mechanism 100 for feeding a flexible substrate tape of the present application can conveniently adjust the channel 101 through which the supply tape passes by the first guide wheel 1 and the second guide wheel 2. During the process of winding and collecting the tape by the production device using the above automatic material collecting mechanism 100 for feeding a flexible substrate tape, even if the reel is slightly deformed or displaced, the established tape can smoothly enter the reel and be wound and collected through the position adjustment of the tape, reducing the on-site downtime and material loss and improving the production efficiency.
